I got Blue version from my Grandad when I was 4. Pretty much taught myself to read so I could play pokemon, since Dad kept refusing to translate what things said for me. Originally I named every pokemon I caught CALLUM (my name) because I thought I was showing they belonged to me. Honestly don't remember much about RBY, other than agonising over how Sabrina had an Alakazam and my Kadabra hadn't evolved by level 80.
GSC came out and I got Gold for Christmas. Quickly fell in love with Typhlosion, and once I found it could learn Thunder Punch Ii was pretty much set for life. I completely ignored stats outside of 'My Tyranitar has all over 100 plus it looks badass!'. I was also one of those 'only use 4 attacking moves' type of people - Typhlosion would run something like Fire Blast / Flame Wheel / Earthquake / Thunder Punch. Flame Wheel was there solely for when I didn't want to waste Fire Blast's PP and still KO a grass type.
RSE is my fave generation to date, and all of my fave pokemon come from it (Absol, Milotic, Latias, Mawile). Decided I'd be super hip and use a girl trainer on my Sapphire version. Enter 'Maria' - the champion of RSE with her Lv 100 Absol knowing Thunder / Fire Blast / Blizzard / Hyper Beam. Times my friend, times. I also distinctly remember walking around school (Grade 4 at the time I believe) being the kid that knew everything about pokemon - "Yeah, the secret to catching the Regis is which ball you use. For Registeel it's Ultra Ball, Regice it's Great Ball, and Regirock it's Timer Ball." Needless to say I was a master trainer.
Got Pearl around Grade 8 I think and DP was the first time I went 'online' to actually see how others were playing the games. Blew my mind at how wrong I had been playing to date, and quickly found my Friday / Saturday nights staying up until 3am on Serebii and Pokecommunity learning everything I could.
Funnily enough, even in my current playthroughs and knowing what I know, I very rarely use anything other than a 4-attack / 3-attack + status moveset. I grind so much between gyms that boosting moves DO essentially become useless, and outside of CM on Gardevoir in RSE or DD on Gyara in DP, it was (and somewhat still is) a 4-attack moveset. Because let's be honest, how much strategy does a game like X and Y require when EXP Share gets you leveled into the 90's by the time you're battling the champion.
On a side note, does anyone remember the Dragonair on.. Stadium 1 I believe (Lance / Claire's?) That would spam Wrap constantly like it was going out of fashion - in a time where it would stop you from being able to attack, and would finish at the END of a turn, just in time for it to use Wrap again.
